Description

Straw mixed fertilizer returning operation machine

technical field

The utility model relates to a straw returning machine tool, in particular to a straw mixed fertilizer returning operation machine.

Background technique

In the spring corn area in northern my country, there is a large amount of straw in the field after the corn seeds are harvested. The straw covers the ground and cannot rot after winter, which brings great difficulties to the autumn plowing and land preparation. This not only reduces air pollution, but also wastes resources. Burying a large amount of straw into the ground will not affect spring planting, but will also increase soil organic matter and fertilize the soil. In the past, high-speed deep plows were generally used to bury the straw in the ground. This method of simply burying the straw in the ground requires a certain amount of N to form its own body when the microorganism decomposes the corn straw, so it is necessary to adjust the content of the straw itself. The ratio of C to N, if the ratio is not adjusted, microorganisms will absorb a large amount of N from the soil when they decompose the straw. This will compete with crops for N, resulting in yellow and dead seedlings. In order to solve this problem, when the straw is returned to the field, add mixed fertilizers to the straw to achieve the purpose of adjusting the ratio of C and N in the straw itself. In the past, chemical fertilizers were applied manually when straw was returned to the field. It requires a lot of labor and the fertilization is uneven.

Utility model content

The purpose of the utility model is to solve the above-mentioned existing problems, and provide a straw-mixed fertilizer returning operation machine with reduced labor intensity, uniform fertilization and good returning effect.

In order to achieve the above purpose, the utility model adopts the following technical scheme: the utility model straw mixed fertilizer returning operation machine includes a main frame, a transmission system installed on the main frame, and a ground wheel. A straw collector and a straw conveyor are arranged in parallel in sequence. The straw collector is provided with a hammer-claw type crushing rotor. One end protrudes out of the main frame and is provided with a lower outlet. Two fertilizer boxes are arranged in parallel above the upper opening of the material box of the straw conveyor. The lower outlets of the two fertilizer dischargers corresponding to the front and back are in communication with the manure falling pipe, and the lower outlets of the manure falling pipe are located directly above the rotor of the straw conveyor.

As a preferred solution of the present utility model, the rotor of the straw conveyor is a conveying auger, which corresponds to the straw collector in the transverse direction, and a spiral blade is arranged on the mandrel of the conveying auger, which corresponds to the lower outlet of the straw conveyer , the mandrel shaft of the conveying auger is provided with throwing knives in an equidistant helical arrangement.

After adopting the above-mentioned technical scheme, the beneficial effects of the straw mixed fertilizer returning operation machine provided by the utility model are as follows:

The upper opening of the straw conveyor material box of the utility model is provided with two fertilizer boxes juxtaposed front and back. The fertilizer pipe is connected, and the lower outlet of the fertilizer pipe is located directly above the rotor of the straw conveyor. In this way, the stalks crushed and collected by the stalk collector are thrown into the hopper of the stalk conveyor, and the stalks in the hopper are mixed with the falling chemical fertilizer while being transported by the conveying auger of the stalk conveyor. One end of the conveyor is discharged from the outlet and falls into the deep ditch for returning to the field. The whole process is completed by mechanization, which saves labor intensity and mixes straw and fertilizer more evenly. It is more conducive to the decomposition of straw underground microorganisms. The effects of reducing labor intensity, uniform fertilization and good return to the field are obtained.

Detailed ways

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail:

As shown in Figure 1 and Figure 2, a schematic diagram of the structure of the straw mixed fertilizer returning operation machine of the present invention is given, including a main frame 1, a transmission system 2 installed on the main frame 1, and a ground wheel 4. A straw collector 3 and a straw conveyor 5 are successively arranged on the frame 1 in parallel with the front and back in the transverse direction. The straw collector 3 is provided with a hammer-claw type crushing rotor. The opening communicates along the transverse direction, and one end of the straw conveyor 5 protrudes outward from the main frame 1 and is provided with a lower outlet. The reducer of the transmission system 2 turns the power to 90° output through the horizontal output shaft, and the output pulley is connected to the input pulley of the hammer-claw type crushing rotor of the straw collector 3, and the upper opening of the material box of the straw conveyor 5 is provided with front and rear side by side. Two fertilizer boxes 7, the bottoms of the two fertilizer boxes 7 are respectively equipped with fertilizer dischargers 8, and the two fertilizer discharger shafts parallel to each other are connected by a transmission chain, and one of the fertilizer discharger shafts is connected to the ground wheel 4 drive shaft. connected by a chain. The lower outlets of the two manure dischargers 8 corresponding to each other are in communication with the manure falling pipe 9 , and the lower outlets of the manure falling pipe 9 are located directly above the rotor of the straw conveyor 5 .

As a preferred embodiment of the utility model, as shown in Fig. 1, Fig. 2 and Fig. 3, a schematic diagram of the specific implementation of the rotor conveying auger of the straw conveyor of the straw mixed fertilizer returning operation machine of the present utility model is given. The rotor of the straw conveyor 5 is a conveying auger, corresponding to the straw collector 3 in the transverse direction, and a spiral blade is arranged on the mandrel of the conveying auger, corresponding to the lower outlet of the straw conveyer 5, and the conveying auger On the mandrel, equidistant helical arrangement is provided with throwing knives 6.

When in use, first connect the three-point suspension frame on the main frame 1 of the straw mixed fertilizer returning operation machine to the tractor suspension mechanism, and the tractor power output shaft is connected to the reducer input shaft of the transmission system 2 through the cardan shaft. After the unit enters the ground, start the power output shaft and drive the hammer claw crushing rotor of the straw collector 3 and the rotor conveying auger of the straw conveyor 5 through the transmission system 2 to rotate. The high-speed rotation of the crushing rotor cuts and smashes the straw. Under the action of high-speed airflow, the straw is picked up, and the collected straw is thrown into the material box of the straw conveyor 5. At the same time, the fertilizer is passed by the fertilizer discharger 8. Falling fertilizer pipe 9 enters hopper. The stalks in the hopper are mixed with the falling chemical fertilizers while being transported by the conveying auger of the stalk conveyor 5, and finally discharged from the outlet at one end of the stalk conveyor and fall into the deep ditch for returning to the field produced by the ditch plow.
